Cyclamen species (swinebread spp.) are perennial herbaceous plants which belong to the Primulaceae family, widely used as medicinal or ornamental plants. Currently, gibberellic acid (GA3), an environmentally friendly bioregulator is enhance productivity and phenotypic characteristics of multiple crops. A dual experiment was conducted evaluate influence (50, 100 150 mg/L), on germination earliness seeds, along with growth quality selected species. Additionally, a greenhouse long short sunlight photoperiod its importance in development Our results indicated that under exposure, seeds germinated earlier than those kept photoperiod. Plants treated foliar applications GA3 exhibited higher plant height, leaf area, number leaves, root length tuber development. Significant differences were found percentage (GP), mean time (MGT) seedling vigor index (SVI), within different supplementation intensity (short days). In conclusion, our study suggests can be increased by application, economic strategy for enhancing
